“…Only a 3D acquisition would provide a complete dataset that would allow for an exact compensation of the displacement of the structures under analysis. The feasibility of perfusion analysis using 3D echocardiography is stressed in some recent studies [39]. One of the problems of working in 3D is the difficult visualization of the data; Yao et al [ 40] proposed a bull's-eye view to present perfusion defects.…”

“…Before the development of real-time 3D imaging, 3D assessment of myocardial perfusion remained limited to visualization of perfusion defects [44] or included measurements of their size [29]. Quantifying tissue blood flow would require repeated contrast maneuvers, such as bolus injections, that are necessary to assess flow dynamics for each imaging plane, rendering this methodology clinically inapplicable.…”

The introduction of three-dimensional (3D) imaging and its evolution from slow and labor-intense off-line reconstruction to real-time volumetric imaging is one of the most significant developments in ultrasound imaging of the heart of the past decade. This imaging modality currently provides valuable clinical information that empowers echocardiography with new levels of confidence in diagnosing heart disease. One major advantage of seeing the additional dimension is the improvement in the accuracy of the evaluation of cardiac chamber volumes by eliminating geometric modeling and the errors caused by foreshortened views. Another benefit of 3D imaging is the realistic views of cardiac valves capable of demonstrating numerous pathologies in a unique, noninvasive manner. This article reviews the major technological developments in 3D echocardiography and some of the recent literature that has provided the scientific basis for its clinical use.

“…In RT3D echocardiography, a 2-D array transducer is used to steer and focus the ultrasound beam over a pyramidal-shaped volume rather than a single-sector scan [12], [13]. Recent studies have demonstrated the effectiveness of RT3D echocardiography for the monitoring of left ventricular function [14], detection of perfusion defects [15], reduced scanning times in dobutamine stress echo exams [16], guidance of right ventricular endomyocardial biopsy [17], measurement of peak left ventricular flow velocities [18], and evaluation of congenital cardiac abnormalities [19].…”
